[0035] Preferably, see Attachment Figure 3 , Attachment Figure 6 Two storage boxes 52 are placed on the lower side of the storage cavity 21, and two cover plates 53 are respectively installed on the upper sides of the two storage boxes 52. The two discharge cavities 51 are respectively connected to the interiors of the two storage boxes 52 and are provided with two discharge ports 54. The interior of the cylinder 22 is connected to the interior of the circular tube 24 and is provided with a first opening 56. The interior of the circular tube 24 is connected to the interior of the fixed frame 49 and is provided with a second opening 57.

[0036] Specific use of the present invention: When it is necessary to extract the fluid from the patient's abdomen, the medical staff inserts the puncture needle 17 into the patient's abdomen so that the puncture needle 17 contacts the abdominal fluid. The control system controls the first stepper motor 26 to rotate forward and reverse alternately. The first stepper motor 26 starts to drive the screw rod 29 to rotate, and the screw rod 29 contacts the movable plate 28 through the outer side of the screw rod 29. The screw rod 29 rotates forward and reverse alternately, thereby driving the movable plate 28 to move up and down. The movable plate 28 moves up and down, driving the first annular plate 32 and the second annular plate 33 to move up and down. The first annular plate 32 and the second annular plate 33 move upward in the cylinder 22, thereby forming a negative pressure on the lower side of the cylinder 22, so that the patient's abdominal fluid can be drawn into the cylinder 22 through the puncture needle 17 and the drainage tube 15, thereby having a traction force on the patient's abdominal fluid and improving the drainage effect. The first annular plate 32 and the second annular plate 33 move upward in the cylinder 22 to exhaust air from the upper portion of the cylinder 22 through the air vents 23 and the slide groove 30 , and the elastic waterproof cloth 31 is used to block ascites from entering the slide groove 30 .

[0037] At the same time, the first annular plate 32 and the second annular plate 33 move downward to squeeze the ascites inside the cylinder 22 through the first opening 56 into the circular tube 24, and the ascites in the circular tube 24 enters one of the discharge cavities 51 through the second opening 57, and the ascites in one of the discharge cavities 51 enters one of the storage boxes 52 for storage through the discharge opening 54. When the ascites in one of the storage boxes 52 is full, the control system controls the second stepper motor 66 to start, and the second stepper motor 66 starts to drive the second bevel gear 67 to rotate, and the second bevel gear 67 engages with the first bevel gear 65, thereby driving the rotating shaft 64 and the circular tube 24 to rotate. The rotation of the circular tube 24 connects the second opening 57 with the other discharge cavity 51, so that the ascites in the circular tube 24 enters the other discharge cavity 51 through the second opening 57, and the ascites in the other discharge cavity 51 enters the other storage box 52 through the discharge port 54, which can continuously extract ascites from the patient's abdomen. The storage box 52 can be replaced without stopping the drainage, thereby improving the efficiency of ascites drainage.

[0038] Secondly, the movable plate 28 moves up and down, driving the first annular cavity 35 and the second annular cavity 36 to move up and down, and contacts the outer thread of the round tube 24 through the inner side of the internal thread ring 34, so that the second annular plate 33 moves up and down and rotates, and the rotation of the second annular plate 33 drives the annular block 38 to slide in an annular manner inside the first annular plate 32, so that the second annular plate 33 rotates smoothly. The second annular plate 33 moves up and down and rotates, driving the first frame 40, the piston plate 41, the elastic rod 42, the first scraper 43, and the second scraper 45 to move up and down and rotate, and the second scraper 45 moves up and down and rotates to clean the inner wall of the cylinder 22; and when the first scraper 43 moves downward and contacts the inner side of the guide ring 55, the first scraper 43 rotates to scrape off the ascites attached to the inner side of the guide ring 55. At the same time, the second annular plate 33 moves up and down and rotates to drive the second frame 46 and the first hollow elastic member 47 to move up and down and rotate. The first hollow elastic member 47 moves up and down and rotates to wipe the outside of the circular tube 24, thereby cleaning the ascites adsorbed on the outside of the circular tube 24.

[0039] Then, the second annular plate 33 rotates to drive the first frame 40 and the push rod 39 to rotate, so that the push rod 39 slides in an annular groove 62, and the upper end of the push rod 39 slides in contact with the lower side of the guide block 63, so that the push rod 39 and the piston plate 41 move downward under the guidance of the guide block 63, and the piston plate 41 moves downward to compress the spring 44 to generate elastic force. When the upper end of the push rod 39 is out of contact with the lower side of the guide block 63, the piston plate 41 and the push rod 39 move upward to reset under the elastic force of the spring 44. So that under the guidance of the guide block 63 and the elastic force of the spring 44, the piston plate 41 moves up and down to a large extent, and the piston plate 41 moves up and down to drive the elastic rod 42, the first scraper 43, and the second scraper 45 to move up and down, and the second scraper 45 rotates and moves up and down to a large extent, which is conducive to improving the cleaning effect of the second scraper 45 on the inner wall of the cylinder 22. The piston plate 41 moves downward to cooperate with the first scraper 43 to contact the inner side of the guide ring 55, thereby squeezing the elastic rod 42, increasing the contact degree between the first scraper 43 and the inner side of the guide ring 55, which is beneficial to improving the cleaning effect on the inner side of the guide ring 55.

[0040] At the same time, the upper end of the push rod 39 is in sliding contact with the outer side of the protrusion 68, so that under the guidance of the protrusion 68 and the elastic force of the spring 44, the push rod 39 and the piston plate 41 are slightly shaken up and down, so that the piston plate 41 is moved up and down by a large amplitude and shakes up and down by a small amplitude at the same time, which is conducive to further improving the cleaning effect of the second scraper 45 on the inner wall of the cylinder 22. At the same time, the piston plate 41 moves downward to squeeze the solution in the first frame 40 into the first hollow elastic member 47, and the first hollow elastic member 47 expands to squeeze the rubber block 48, so that the rubber block 48 is squeezed and contacted with the outer side of the round tube 24, which is conducive to improving the cleaning effect on the outer side of the round tube 24.

[0041] Next, the movable plate 28 moves downward to squeeze the second hollow elastic member 27, so that the cleaning liquid in the second hollow elastic member 27 is squeezed through the connecting channel 37 into the first annular cavity 35, and the cleaning liquid in the first annular cavity 35 enters the second annular cavity 36. A part of the cleaning liquid in the second annular cavity 36 is sprayed out to the outside of the circular tube 24 through a plurality of first spray valves 58, and another part of the cleaning liquid in the second annular cavity 36 is sprayed onto the inner wall of the cylinder 22 through a plurality of second spray valves 60, so as to perform a flushing and cleaning function on the inside of the cylinder 22. The movable plate 28 moves upward, and the second hollow elastic member 27 restores its shape to draw the cleaning liquid in the box 25 into the second hollow elastic member 27 to replenish the cleaning liquid, so that the movable plate 28 moves up and down to cooperate with the elasticity of the second hollow elastic member 27, so as to continuously replenish the cleaning liquid in the box 25 into the second annular cavity 36, and continuously flush and clean the inside of the cylinder 22, thereby improving the efficiency of cleaning the inside of the cylinder 22 and avoiding affecting the use efficiency of the ascites drainage device.

[0042] Finally, the storage box 52 can be taken out from the storage cavity 21 for replacement. The storage box 52 can be replaced without stopping the drainage, thereby improving the efficiency of ascites drainage.
